In a world where bizarre, reality-warping 'Pollution' has become a normalized nightmare, Ding Mo finds himself trapped in a cycle of madness. After a mysterious incident in 2020, society has been slowly eroded by inexplicable phenomena—people wearing masks as faces, walking naked in public, and worse. Five years later, Ding Mo is thrust into a lethal game of survival.

Forced to operate a cursed typewriter that manifests reality, he is suddenly pulled into a parallel, fog-shrouded dimension. Now, he must survive as a taxi driver in a world where the rules of logic have been replaced by the 'Handbook' of the supernatural. To stay alive and maintain his sanity, Ding Mo must perfectly embody his assigned roles, acting out identities to keep his 'Threshold' from collapsing.

In a land where passengers are made of paper and traffic cops are harbingers of doom, Ding Mo realizes a terrifying truth: to survive the pollution, he might have to become the very thing he fears.
